11 claims. (o1. z2-118)" This invention relates to an improved means for furring in connection with cast concrete structures of various kinds; and the invention has reference, more particularly, to a novel supporting hanger adapted to be molded into and bonded to the concrete mass when the latter is cast.

This invention has for its principal object to provide a simple and eiective type of hanger for supporting furring in connection with concrete structures; the same being of such form as to be capable of rapid and easy initial attachment to the forms in which the concrete is cast, whereby, upon removal of the forms, the hangers Will be iirmly and securely imbedded and anchored in the concrete mass, and will, when so aixed to the latter, provide freely projecting hanger arms through which furring material, such as rods,

to be supported alongexterior surfaces of the concrete ready for use in attaching thereto ceilings, lintels, slabs or other superimposed structures.

Another object of this invention is to provide a novel type of furring support or hanger adapted to be initially mounted in connection with concrete casting forms preparatory to pouring the concrete; the support or hanger having a gauging or stop portion to coaet with the forms so as to uniformly predetermine the projection of the hanger arm from the cast concrete mass.

Another object of this invention is to provide a type of furring support or hanger which, as initially attached to the casting form, is stabilized and rmly secured and supported against accidental displacement pending the casting of concrete in the form.

Another object of the invention is to provide aA furring support or hanger so devised and arranged and so related to the casting forms that,v

when the casting forms are removed, thehangers will be ready for the reception of furring without necessity of make-ready operations to bring the same into final operative positions preparatory to attaching the furring material thereto.

A further object of this invention is to providev a furring support or hanger for the purposes de-V scribed, but which also aliords means for supporting and positioning concrete reenforcing rods in desired spaced relation to the sides and more particularly enumerated, will be understood `from the following detailed Same.

Similar characters of reference are employed in the above described views, to indicate correspending parts..`

Referring to the drawings; the preferred form Y of furring support or hangeris shown in Fig. 5; the same being made of a metallic strip or strap of suitable width and thickness, as e. g. a width of apprommately one inch, and a thickness of approximately from one-sixteenth to oneeighth of an inch, although it will be understood that these measurements are not critical, but are suggested as adequate for the average conditions of use; If massive structures are to be erected, the size and proportions of the hanger devices may be increased; and, on the other hand, for light structures, the size and proportions of the hangerA devices .may be reduced. The novel hanger device comprises a base or foot portion 10. Formed at the outer end of said base or foot portion 10 is an upwardly extending anchor loop 11 of an inverted substantially U-shape. The outer leg of said anchor-loop 11 is extended downwardly for a substantial distance below the plane of said base or foot portion 1,0, to provide a depending hangerl arm 12.; Struck from said hanger arm 12 is an up-turned Vinwardly projecting gauging or stop lug 13, disposed to'projectY substantially at right angles thereto and to lie in the plane of said base or foot portion 10. The

removal of said gauging or stoplug .13 from the' body of said hanger arm 12 provides the'latter with an opening or eye 14 adapted in use to receive and support a furring 'rod or the like. Formed in the base or foot portion 10, so as to be laterally off-set from a line extending through the center of said opening or eye 14 is a nail hole 15.

v Referring now to Fig. 1 of thev drawings, there is shown, therein an arrangement, of forms for casting a building iioor '16 having integral beam portions `17 depending from its under side, in connection with which are arranged'the novel furring supports or hangers of this invention, wherebythe use of the latter is illustrated. These casting formscomprise girder timbers 18 aligned substantially centrally of the desired locations of the beam portions 17. Supported by and upon said girder timbers 18 are the beam bottom floor boards 19. ASecured to the side faces of said girder timbers 18 are ledge pieces 20, upon which are supported, to extend between said girder tim.- bers 18, bridge boards 21 which are adapted to support the metal arch pans 22, whereby the latter are operatively disposed to dene the sides ofthe beam portions 17 and the floor bottom arches 23 extending therebetween. Fixed on said bridge boards 21 are positioningbattens 24 to engage'and retain the arch pans 22 against accidental lateral displacement or shifting pending the casting ofv concrete into the form.

n After the timbering and beam bottom boards of the casting forms have been erected, and prior to the insertion of the arch pans 22 and their supports to complete the forms, the hangendevices,l of this invention are: mounted upon and temporarily attached to the bea-m bottom floor f boards 19. In sofmounting the hanger devices,

each of the same vare disposed with their base or foot portions l0 footed upon the upper surface of the beam bottom oor boards 19, with their anchor-loops 1l toward the margins of the latter,

-- and with their hanger arms 12 extending downwardly over the` edges of said boards 19, but having, their` gauging or stop lugs 13 abutting the upper surfaces of said boards 19. The hanger devices may be mounted in spaced apart relation according ,to the desired distance of spacing desired as to the furring material to be installed. Tofretain the hanger devices in place nails 25 are drawn downwardly ythrough the nail holes 15 thereof into the boards 19. When the hanger devices are mounted in the mannerv described, the

same are firmly footed upon the boards 19, and by reason off-the engagement of the latter by the gauging or stop lugs 13, the same are not only firmly vbraced against downward tipping or other displacement, but the extent of downward projectionof the hanger arms 12 is predetermined and is maintained uniform in relation one to another so that thefurring rod receiving openings or eyes 14 thereof'are operatively aligned from one. beam to anotherereadyqforthe.insertion therethrough of the furring rods. It will be understood that the hanger devices may be mounted along either one or both margins of the boards 19, as may be deemed desirable.

Upon setting of the hanger devices and completion of the forms, the concrete is cast into the latter to mold the building floor 16 and its integral beam portions 17. `As the uid concrete is cast into the forms, the same ilows downwardly over the base or foot portions 10 of the hanger devices and into and around the bights of the anchor-loops 1l thereof, so that, when the concrete hardens, the latter will be firmly imbedded and anchored in the concrete mass, so as to hold the hanger devices immovable.

Upon removing the arch pans 22 and their supports, the girder timbers 18 may be removed, and

14 of the exposed hanger arms12 so as to be 1 supported thereby for extension in desired spaced apart relation beneath and across the bottom faces of the beam portions 17. To the furring rods 26, as thus supported across the under side of the iioor structure, metallic ceiling 28 is applied in the usual manner.

f Referring to Fig. 6 or the drawings, I have shown therein a hanger device of somewhat modied shape, wherein the anchor-loop 11', which extends from the forward end of the base or foot portion 10', is of regular shape, with its front leg perpendicular and its rear leg inclined. This shape is better adapted for use in connection with floor beam portions in which reenforcng rods are employed, since it better permits the latter to be disposed adjacent to the sides and bottom 'of said iloor beam portions. The gauging or stop lug 13', shown in connection with the hanger arm 12 of this modied form of hanger device, is of substantiallyv circular form to provide a round eye 14', if such form is. desired.

Referring to Figs. 7 and 8 of the drawings, I have shown therein, a modified form of hanger device having in its hanger arm 12 an opening or eye 14 enlarged to accommodate iurring 29 of the channel bar type.

. It will be understood with respect to the various forms of hanger devices that the length of the hanger arm 12 may be increased if it is desired tov more distantly space the lath and plaster from the under side of the floor structure; in whichcase the openings or eyes 14 are located accordingly. I

Referring to Figs. 9 and 10. of the drawings, I have shown another modification of the novel hanger device which serves the additional function of supporting concrete reenforcingrods preparatory to casting the concrete structure. This form of hanger device comprises an anchor loop in the form of a raised main body or bridge-piece 30 having at its inner end a downwardly projecting leg or foot-piece 31 and at its outer end a downwardly projecting leg 32 terminating in a hanger arm 33. Struck or bent from said hanger arm 33 is an upturned inwardly projecting gauging or stop lug 34 disposed to lie substantially in the plane of the free end of said leg or foot-piece 31. The displacement of said gauging or stop lug 34 fromthe body of said hanger arm 33 provides the latter with an opening or eye 35 adapted notched as at 33.

in use to receive and support a furring rod or the like. Formed in the body or bridge-piece 39, so as to be laterally oil-set from a line extending through the center oi said opening or eye 35 is a nail hole 36. Struck into upstanding relation to the body or bridge piece 3G, preferably from opposite sides thereof, so as to be spaced apart a desired distance longitudinally of said body or bridge are rod-rest lugs 37, the'upper free ends of the same being preferably somewhat indented or This combined hanger device and reenforcing rod support is used as follows:

' When the girder timbers 18 and the beam bottorn floor boar-ds l9 are set up, the hanger devices are mounted and temporarily attached to tne latter in spaced apart relation along the same. Each hanger device is set transversely ci the floor board 19 so as to extend across almost the full distance of the width of beam to be cast. As so disposed, the leg or foot-piece 3l rests upon the floor board 19 adjacent to one margin thereof, while the opposite leg 32 is positioned to dispose the hanger arm 33, extending therefrom, downwardly over the opposite margin or" the floor board i9, with the gauging or stop lug 34 abutting the upper surface of said floor board, thereby spacing the body or bridge-piece 30 above and substantially parallel to the floor board so as to forno an anchor-loop portion adapted to be imbedded in the concrete mass of the beam, when the latter is cast. To hold the device in place preparatory to casting the concrete, a fastening nail 39 driven downwardly through the nail hole '35 and into the floor board 19.

When the hanger devices are thus mounted, reeniorcing rods all may be mounted across the same upon the rod-rest lugs 37, as shown in Fig. 9, thus supporting said rods 40 in properly spaced relation to the sides and bottom of the beam preparatory to the casting thereof, and so as to be imbedded in said beam when it is cast. Upon removal of the forni material after the floor structure and its beam portions are cast, the body of the hanger device will be firmly imbedded and anchored in the rnass of the concrete, while the hanger arm 33 will project downwardly and exteriorly from the latter, ready to receive and support the fuiring material substantially in 'the manner as already above described.
